How to use this tool
Prefer a complete URL before parsing and editing the rows. Query-only or invalid input can fall back to example.com during construction, so inspect the resulting host before using the address.
Results and examples
?tag=a&tag=b can retain two rows with the same key. A value containing a space may serialize with + under URLSearchParams rules rather than preserving the original byte spelling.
Limitations
- Reordering or re-encoding a signed URL can invalidate its signature.
- Check for credentials and personal data before sharing the generated address.
